h1. FEI Talos installation specifics h2. Install win32 version of python subpackages Because all interaction with the scope uses COM interface that is only accessible through 32-bit architecture, python running Leginon component is the 32-bit version. Use the 32-bit Windows files (those marked as win32 and certainly not the ones says 64) in http://emg.nysbc.org/projects/leginon/files for these. *Talos has a 64-bit Python pre-installed unde default On-system UI uses 32-bit python location C:\Python27. as well*. Therefore, Therefore we just need to name our installation with another name, such as C:\Python27-win32.* install the dependency that is missing in there. The location of this python is <pre> C:\Tecnai\OnSystemUI\Python27 </pre> Here is the full list {{include(Windows_32_External_Package_Installers_Common)}} {{include(Comtypes_installer)}} h2. Important: Install Python under a custom named folder *Talos has a *If the system comes pre-installed with 64-bit Python pre-installed unde default python location C:\Python27. as well, some of these packages may get confused.* During these installations, keep an eyer on where the packages are installed into. Therefore, we need If it attempts to name our installation with another name, such as C:\Python27-win32.* This is set during install into the 64-bit python installation. at C:\Python27, contact Leginon Team through Forum. The rest of the installation is similar to other FEI systems. h2. (Strongly recommended) Use local myami folder to run Leginon Because we install into FEI's framework folder, it may be erased at the next upgrade by the service engineer. To reduce the possibility of loss of local modification, we recommend using local myami checked out from NRAMM svn repository directly as follows, rather than installed into python's site packages. {{include(Set_pythonpath_environment_variable_for_local_myami_sandbox)}} h2. instruments.cfg cs is *constant for sperical abberation* For Tecnai series: <pre> [TEM] class: tecnai.Talos cs: 2.7e-3 </pre> h2. Testing with pyscope In python command <pre> from pyscope import tecnai t = tecnai.Talos() t.getMagnification() </pre> h2. Trouble Shooting [[unable to initializ Tecnai interface error]] h2. Programs to open before Leginon Client: None
